Hello,
Can someone help me to understand the xfade filter documentation regarding
custom expressions. I'm not really sure how to express a transition given
the variables provided.
"XY - The coordinates of the current sample." - Is the transition defined
by selecting a color/state for each pixel?
Dear all,
I am having so many issues trying to clip a video with KLV. When I edit a video
with KLV I lose the KLV.
I have read about -map 0 option, from my understading it copies all the streams
of a video from the input 0.
The command I have tried and it is not working is the following:
Hey !
I'd like to get the full power of the VP9, but I need to use batch list
to not lose anytime.

That's not a good error description. ;-) What did you expect, what was
the outcome, what went wrong?

Dear all,
I guess I found the problem why it was not working. My KLV stream is the stream
1
See the log,
[mpegts @ 026b6a21c380] start time for stream 1 is not set in
estimate_timings_from_pts
How can I set the start time just for the stream 1??

Hey !
Thank you for your answer ! I think I did a lot of mistake in my shell...
It's working like I wrote it, as you said : "basically correct". I'll
add : "definitly correct" ! Hope that thread will help peoples. Because
I was driving nuts all morning long.
The main problem I had is that it
Thanks Motitz,
this is a one pass norm.
Is there a way to implement 2 pass?
Thanks.

Dear All
I don't know how to read a h264 network stream with ffmpeg.
I create the stream on a Raspberry Pi with this command:
raspivid -t 0 -b 1000 -n -o test.h264
I am able to view the video with ffplay:
ffplay -i test.h264

Hi,
I have a video with 45 minutes duration. This video contains 2-5 breaks.
Each break time lasts 10 seconds. At this time, the screen is completely
black. But, we can see a watermark and time code clearly. So I want to get;
1. The start and end time of this black screen break.
2. The time code on

You could probably do this in two passes.
The first using the select filter to find the timing of each new image.

I've searched the web for infos about which graphics card/GPU to get for

I think “-fflags nobuffer” tells ffplay not to buffer? So there will be nothing

Ted,
I did try without that buffer flag, but that had no effect. I’m going to try
updating ffplay, and see if that helps.
Also, I’ve noticed that vlc had a 1000 ms “network cache”, and I wonder if that
had anything to do with playing that station flawlessly.

I totally overlooked the text and thought "path" and "domains" are just the
